Total Galactic extinction Map (gaiadr3.total_galactic_extinction_map)
The table has 4177920 rows, 10 columns.
Description
This table provides the Total Galactic Extinction (TGE) map for extinction parameters A0 describing the effective total Galactic extinction and related uncertainties at four separate HEALPix levels, namely levels 6 to 9. For further details see Section cu8par_apsis_tge of the online documentation.
